A. K; MALMQulsT Y cANNING APPARATUS v v original Filed August 18, V1922 sjsheetsfsheets A TPP?- f E T-f A. K. MALMQUIST CANNING` APPARATUS original Filed August 18, 1922- 6 Sheets-Sheet 6 sleeve 19 forming part of the table structure 5. The gear 17 is constantly driven, and thus motion is transmitted to the can feed disk 12 to continuously rotate the same.

Open cans which may contain solid food may be delivered by any suitable means (not shown) to the revolving feed disk and the cans will be carried by said disk between guides 20, 21 disposed over the disk. The guide 2O is provided with a boss 22 secured to one of the posts 10 and at one end of the guide 20, a curved guide 23 is provided. The

guide 21 is made rigid with a plate 24 (Fig.

5) having apart near the guide 21 through which the shank at the upperend ofthe shaft 11 passes. The plate 24 is secured to the table structure 5 as shown at 25 and projects into the structure of the can'perfecting mechanism as indicated at 26, and said mechanism will operate to shape an imperfect feed canv such as shown at x Fig. 12

Y so that it will appear as shown at y Fig. 13.

The part 26 of the plate 24 is'made with a lateral arm 27 which enters a groove 28 (Fig. 2) in a central tubular column ofr a spider 29 in said can-perfecting structure. At one end, part 26 of the plate 24 is provided'with a guide flange 30 spaced from the straight portion of va guide 31 toform a guideway 32, and said guide 31 is provided with a plate member 33 secured tothe table structure 5, as shown in Figures 5 and V6.

The rotating ydisk will operate to move alcan in front of superimposed levers 34 and 35 carried by a vertical shaft 36 mounted in the table structure 5,-the lever 34 being fixed to said shaft and the lever 35 being' mounted loosely thereon. A latch 37 is mounted on the loose lever 35 andis normally maintained out of latched engagement with a shouldered portion 38 of the lever 34,y

. 4by the action ofa spring 39, said y'latch be- CTI ing` provided with a lever or trip arm 40 dis` posed in the path of a can on the rotating feed disk 12. vTo the lower end portion of the shaft 36, a crankarm 41 is secured and carries a pin 42 which is connected by a link 43 with an eccentric 44 carried by the lower end of a vertical shaft 45 mounted in the table structure 5,-said shaft being provided at its lower end with a gear 46 which receives motion from the gear 17 (see Figures 3 and 6). With such construction theV shaft 36 will beoscillated continuously, the upper lever 34 moving back-and-forth over the can path while the lower loose lever 435 will-remain normally at rest; lVhen a can v is fed forward by the constantly rotating feed disk 12, said can will engage the latch lever 40 and the two levers .will become latched together so that the lower lever 30 will move forwardly with the upper lever 34 and feed the can to the can-perfecting mechanism. Vhen this shall have been accomplished, the spring 39 will operate to disconnect said levers, and as the upper lever 34 recedes it will engage an arm 47 on the loose lever 35 and cause the latter to be returned to its normal idle position. In order to prevent the lever 34 from dragging lever 35 until a can couples lever 34 with latch lever 40, the lever 35 is provided with a spring-pressed holding pin 35a having a rounded lower end to engage in a depression 35b in the underlying plate as shown in Figure 6.

When a can is moved into the can-perfecting mechanism as'above described, it will become deposited uponl one of a seriesrof can n"supporting platforms or pockets 48, each of which is made with a lateral extension 49 to facilitatethe subsequent discharge of the can and each of said platforms or pockets is made with a groove 50 for the accommodation of the bottom' flangeI of a can, as shown in Figures '4,' 7, 8 and 14 to 17, The platforms or pockets 48 are providedY with depending shanks 51 entering sockets in the upper .ends of plungers 52and pinned to the latter, as at 53. vertically movable through suitable holes in arms 54 on the spider 29, and each plat-V form or pocket 48 is made with an extenf sion 55' which carries a guide rod 56 entering a hole 57 in one of the; spider arms 54. Each plunger 52 carries near its lower end, a roller 58 to cooperate with a grooved cam 59 secured to the lower fixed bracket 7, for raising and lowering the platforms or pocketsand the can thereon relatively to therdevices located abovethe same which operate to straighten or perfect the open flanged upper ends of the cans. Y

The can raising and lowering devices and the straightening or perfecting devices -above referred to constitute one ofthe units Gef the can perfecting mechanism, and in the apparatus illustrated .in the drawings, siX such units are employed, andthe movable parts `o'feach of said units are carried by the lraised by the raising of the can platformsV t' or pockets 48. A driving shaft 64 for the' spider 29 passes through the central tubular portion of the latter and is pinned toA the sameas indicated at 65,-the upper pori tion of said shaft being-mounted in a bear-v ing 66 depending from the upper bracket 9. The lower through the enlargement 61 on the lower bracket 7 anda gear'67 is keyed to its depending end and provided with a threadl rThe plungers 52 arel portion of the shaft passes` Shank which rebevellolding @Sand ing interposed between'saidlgear gandgthe lower bracket 7 and enelosed leva an-ge 10a the medinm of thegears` 46 andl 17 from` large. gear '7F11 andthe latter." isjldriven throu'gh the' ined' t Y The devices for from av drivingrshaft, not` shown.
